It has the benefit of putting something in your mouth, and preserving the smoking ritual. Which is as important for many smokers as nicotine.
It's not without reason that it became so popular in the few years since it went mainstream.
To be clear it has become popular as a substitute for (or adjunct to) smoking. As a quitting aid it isn't especially effective, even if slightly more effective than NRT.
I must say in my practice I haven't seen anyone quit using vapes, it just becomes a substitute.
I've quit both, and the first step was controlling the amount of nicotine I was inhaling. Once that went away I weened off all the other little triggers and cravings I want even aware of until I got hit with them.
Thankyou, I have been relying on an article I read several years ago, which in my memory was Cochrane also, I may be able to track it down. Turns out I'm out of date on that stat.
I stand by it having uncertain long term consequences when other forms of NRT are proven safe.
Buy the gum and patches as additional options. The ritual of putting cig to mouth is incredibly strong, especially if there are social factors in play.
You can't make someone quit your way, they have to quit their way.
